COIN-DETECTOR FOR AUTOMATIC VENDING-MACHINES.

SPECIFICATION formingpart of Letters Patent No. 564,824, dated July 28,1896. Application filed November 20, 1895. Serial No. 569,500. (Nomodel.)

To all whom it may concern.-

Be-it known that I, ALEXANDER J AEGER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inCoin-D etectors for Automatic Vending Machines, of which the followingis a full, clear, and exact specification.

My invention relates to a new and useful improvement in coin-detectorsfor automatic vending-machines, and has for its object to so constructsuch a device as to render impossible the passage of iron or steel disksto the money-drawer of the vending-machine, even though said disks be ofa size which exactly corresponds with the coin intended to be used inoperating the mechanism of the machine and, further, to discharge disksthat have been detected to one side of the chute and outside of thetrough by the insertion of the next coin or disk.

VVit-h these ends in view the invention consists in the details ofconstruction and combination of elements hereinafter set forth, and thenspecifically designated by the claims.

In order that those skilled in the art to which my invention appertainsmay understand how to make and use the same, I will describe itsconstruction and operation in detail, referring by number to theaccompanying drawings, forming a part of this specification, and inwhich Figure 1 is a side elevation of my improved mechanism; Fig. 2, asection at the line 00 as of Fig. 1; Fig. 3, a section at the line 3 yof Fig. 1; and Fig. 4, a View similar to Fig. 2, showing the magnet andits attendant parts forced to one side into position assumed when thecoin or disk is being inserted through the slot in the escutcheon.

Similar numbers denote like parts in the views of the drawings.

1 is the ordinary escutcheon, which is secured in the usual manner tothe vendingmachine, and from this escutcheon leads downward and backwardthe primary chute 2, which connects with the secondary chute 3, whichlatter leads to the money-drawer or other suitable receptacle for thecoin which is intended to operate the mechanism of the vending-machine.

Pivoted atin suitable bearings connected with the chutes or other partsof the machine is a permanent magnet 5, having one of its members,preferably the positive, extending downward into close proximity to theguideway formed in the primary chute.

6 is a projection extending upward from the bottom of said guideway, soas to arrest and deflect the movement of the coin or disk in its passagedown said guideway, whereby as the coin reaches this projection it willbe thrown upward, so that its upper edge will pass between the side ofthe magnet and the wall of the chute in such close proximity to saidmagnet as to be within the magnetic field thereof, by reason of which,if the disk be of iron or steel, it willbe drawn into contact with saidmagnet and thereby arrested and prevented from further movement.

'7 is astrip of brass which serves as a shield and is placed immediatelybeneath the pole of the magnet, so that as the latter is swung sidewiseupon its trunnions its magnetic lines will be interrupted by thisshield, for the purpose hereinafter set forth.

A U shaped strip 8 is secured, by means of the screw 9, to the magnet orother part movable therewith, and the-lower member of this strip extendsalong one side of the passage in the chute, in order that the coin willbe prevented from jumping out of said passage when coming in contactwith and being elevated by the projection 6. Secured to that side of themagnet opposite this strip is a push-off 10, the nose of which isadapted to swing to and fro through the slot 11, formed in the side wallof the primary chute, so that when a disk has 'been detected andarrested by the magnet, and said magnet is swung to one side to theposition shown in Fig. 4, this push-off serves to displace the coinsidewise and permit it to drop outside of the primary chute, as will bereadily understood; and, as before described, the shield 7 willinterrupt the magnetic lines of the magnet when the latter is swungsidewise, thereby releasing the disk and permitting the push-off toproject it outside of the chute; or should the disk passed.

I in its upward movement pass above the lower end of the magnetic polethis shield will prevent it from moving with the magnet when the latteris swung sidewise, whereby it will be caused to lose its hold upon themagnet.

12 is an arm which is secured to the magnet and extends forward,terminating in a toe 13, which bears against the lever 14:, which latteris pivoted at 16 to the escutcheon and projects in front of the slot 17,formed in said escutcheon, through which the coins are This lever is soformed that the coin, being forced through the slot, will move itsidewise upon its pivot, and this side movement of the lever will actupon the toe of the arm 12, thereby swinging the magnet and the partscarried therewith sidewise to the position shown in Fig. 4. Thus, if thedisk has been caught by the magnet, as before described, this movement,caused by the insertion of a new coin, will project said disk sidewiseand permit it to fall downward, as previously set forth. In order thatthese false coins or disks may not reach the coin-receptacle, I providea shield 15, so arranged that when a coin or disk falls thereon it willbe deflected to one side and slide into a properlyarranged receptacletherefor. The secondary chute is open upon one side, so that itsguideway is formed by narrow flanges upon either edge, in order that acoin or disk passing down said guideway will drop out if it be of toosmall a diameter, and this is facilitated by the setting of said chuteupon a slight angle to the perpendicular, as clearly shown in Figs. 2and at.

The shield 15 is so arranged relative to this secondary chute as to shedfalse coins, which may drop out of said chute, in order to prevent themfrom clogging the machine.

To insure the return of the magnet and the parts carried thereby totheir normal position, the spring 16 is so arranged as to bear againstsaid magnet, whereby a resiliency is imparted thereto.

Of course it will be understood that genuine coins of the proper sizepassing through the primary chute will not be affected when comingintothe magnetic field, and will therefore ride over the projection 6 anddrop into Having thus fully described my invention, what I claim as newand useful isi 1. A coin-detector for automatic vending machines,consisting of a primary chute and a secondary chute, the bottom of thepassageway of the former being provided with a projection, whereby thecoin is elevated, a magnet pivoted so as to swing sidewise, and havingone of its poles so arranged as to attract an iron or steel disk whenelevated as described, whereby said coin is prevented from passing tothe secondary chute, substantially as and for the purpose set forth.

2. A coin-detector for vending-machines, consisting of a primary chuteand a secondary chute, a magnet pivoted so as to swing sidewise, aprojection formed upon the bottom of the primary chute, whereby coinspassing down said chute are elevated into proximity to the pole of saidmagnet, a lever so arranged relativeito the admission-slot as to beswung sidewise when a coin is pushed into the primary chute, and 'meansfor transmitting a swinging movement from said lever to the magnet,whereby a false coin, detected by the magnet, will be displaced sidewiseand prevented from entering the secondary chute.

3. In an automatic vending-machine, a coindetector, consisting of aprimary chute and a secondary chute, a magnet pivoted so as to swingsidewise and having one of its poles projecting into close proximity tothe passageway in said primary chute, a projection formed upon thebottom of said passage, whereby a coin, passing down said chute, will beelevated within the magnetic field of said magnet, a push-off secured toand swinging with said magnet, a shield for interrupting the action ofthe magnet upon the false coin, an arm 12, projecting from said magnet,a lever 14, pivoted to the escutcheon of the machine in such relation tothe admissionslot as to be deflected sidewis e when the coin is shovedinto said slot, said arm and lever being so related as to transmit aswinging movement from the lever to said magnet, for the purpose ofdisplacing a false coin detected by said magnet, sidewise, whereby itwill be dropped out of the primary chute and prevented from entering thesecondary chute, substantially as and for the purposes set forth.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses.

ALEXANDER JAEGER.
